The graph below could be the graph of which exponential function?
A. F(x) = 3 • (1.2)^x
B. F(x) = 3 • (0.2)^x
C. F(x) = 3^x
D. F(x) = 3 • (-1.2)^x
Answers
First we know it cannot be 3*(-1.2)^x because it would be heading down not up. Then solve for x=0
We know for c 3^0 = 1 so (0,1) but that’s clearly not on the graph in fact the x int is 3 (0,3) so it must be A or B.
Now solve another easy point, where X = 1
Cause that’s just itself , so apply it to A and B
A: (1,3.6)
B: (1,0.6)
And clearly the graph increases in y as x increases. So it must be A.

8. A company sells a product for $15.99 each.
The expenses to make the product this month
totaled $25,000. If they make a profit of $5,381
this month, how many products did they sell?
Answers
Answer:
the company made 1900 products

add the expenses and profit together to get 30381 and divide it by 15.99 since each item sells for 15.99 and you get 1900 products sold
Find the value of y in the solution to the system of equations shown. y=5x+3 2y=18x-10
Answers
Answer:
13
Step-by-step explanation:
To find the value of y, we will use the substitution method
Plug the y of the top equation into the other equation
2(5x + 3) = 18x - 10
Distribute the 2 into the equation inside the parenthesis
10x + 6 = 18x - 10
Subtract 10x from both sides
10x + 6 = 18x - 10
-10x -10x
6 = 8x - 10
Add 10 to both sides
6 = 8x - 10
+10 + 10
16 = 8x
Divide both sides by 8
16/8 = 8x/8
x = 2
Sub the 2 in the place of x into one of the original equations. We will use the first one.
y = 5(2) + 3
y= 10 + 3
y = 13
Answer:
y = 13
Step-by-step explanation:
y = 5x + 3
2y = 18x- 10
substitution (substituting y with the y value given):
2( 5x + 3 ) = 18x - 10
solve:
10x + 6 = 18x - 10
10x - 18x = -10 - 6
-8x = -16
x = 2
now plug in the x:
y = 5( 2) + 3
y = 10 + 3
y = 13

How many committees can be formed by choosing 4 men from an organization of a membership of 15 men?
Answers
The selection of the committee members is an illustration of combination
There are 150150 different ways of selecting the committee
How to determine the total selectionThe number of members (n) is:
n = 15
The members on the committee are (r):
r = 4
So, the number of selection is:
[tex]^nC_r = \frac{n!}{(n - r)!r!}[/tex]
This gives
[tex]^{15}C_4 = \frac{15!}{(15 - 4)!4!}[/tex]
Evaluate the differences
[tex]^{15}C_4 = \frac{15!}{9!4!}[/tex]
Expand
[tex]^{15}C_4 = \frac{15* 14 * 13 * 12 * 11 * 10 * 9!}{9!4!}[/tex]
This gives
[tex]^{15}C_4 = \frac{15* 14 * 13 * 12 * 11 * 10}{4!}[/tex]
[tex]^{15}C_4 = 150150[/tex]
Hence, there are 150150 different ways of selecting the committee

Triangle P Q R is shown. Angle P Q R is a right angle. The length of Q R is p, the length of R P is q, and the length of P Q is r. Which sine ratios are correct for ΔPQR? Check all that apply.
A. sin (P) = StartFraction r Over q EndFraction
B. sin (P) = StartFraction p Over q EndFraction
C. sin (Q) = StartFraction r Over p EndFraction
D. sin (R) = StartFraction q Over r EndFraction
E. sin (R) = StartFraction r Over q EndFraction
Answers
Step-by-step explanation:
answer is in the picture
Option A (sin(P) = r/q), Option C (sin(Q) = r/p), and Option D (sin(R) = q/r) are correct sine ratios for ΔPQR. Option B (sin(P) = p/q) and Option E (sin(R) = r/q) are not correct sine ratios for ΔPQR.
To determine the correct sine ratios for ΔPQR, let's recall the definitions of sine for each angle in a right-angled triangle.
In a right-angled triangle ΔPQR:
1. sin(P) = opposite side / hypotenuse = r / q (Correct) [By definition of sine in a right triangle, sin(P) = opposite/hypotenuse]
2. sin(Q) = opposite side / hypotenuse = r / p (Correct) [By definition of sine in a right triangle, sin(Q) = opposite/hypotenuse]
3. sin(R) = opposite side / hypotenuse = q / r (Correct) [By definition of sine in a right triangle, sin(R) = opposite/hypotenuse]
Option A (sin(P) = r/q), Option C (sin(Q) = r/p), and Option D (sin(R) = q/r) are correct sine ratios for ΔPQR. Option B (sin(P) = p/q) and Option E (sin(R) = r/q) are not correct sine ratios for ΔPQR.
